Description

Technical Field

[0002] Solar energy resources are abundant and renewable. They are clean, safe and easy to use. More and more people are paying attention to them. At present, in the process of replacing coal with electricity in the north, air source heat pumps are gradually being widely promoted in winter. They use the heat in the air to generate thermal energy. They can provide large amounts of water, high water pressure and constant temperature water flow for communities, schools, hospitals, office buildings, shopping malls and other places around the clock. There are more and more large-scale central heating projects with heat pumps, which are installed on the roofs of buildings. However, due to the large number of units and their close proximity, it is easy to cause the cold island effect, resulting in low outdoor ambient temperature on the evaporator side of the unit. When it is lower than the evaporation temperature of the evaporator, frost will form on the surface of the evaporator. Over time, the frost layer will become thicker, which will reduce the heat exchange efficiency of the evaporator, and the evaporation temperature will also decrease, which will reduce the thermal efficiency of the heat pump and reduce the output of heat, affecting the operating efficiency and safety of the unit.

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background technology, with the expansion of the scope of solar energy utilization, air source heat pumps are installed on the roofs of existing buildings to generate heat energy to provide water with different temperatures for people in the buildings. However, since there are many units installed on the top of the building and the distance between them is close, it is easy to cause a cold island effect, which in turn leads to low stability of the outdoor environment on the evaporator side. On the one hand, it is easy to frost, and on the other hand, the heat exchange efficiency of the evaporator is reduced, which in turn affects the thermal efficiency ratio of the heat pump, and ultimately leads to a reduction in the output of heat, which reduces the working efficiency of the air source heat pump. Therefore, the inventor uses the existing heat pump body 1 and installs insulation and noise reduction components on its upper end and both sides to solve the above problems. The following is a detailed explanation with reference to the diagram.

[0029] This embodiment provides a noise reduction and heat preservation component for an air source heat pump, see Figure 1The noise reduction and heat preservation component is installed at the upper end and both sides of the heat pump body 1, and the two sides refer to a group of side chambers of the heat pump body 1 with an evaporator, wherein the noise reduction and heat preservation component includes a first sound insulation barrier 2 installed on both sides of the heat pump body 1, and the height of the first sound insulation barrier 2 is not less than the height of the heat pump body 1, which can ensure that the first sound insulation barrier 2 has sufficient heat preservation and noise reduction range on both sides, and the first sound insulation barrier 2 is spaced apart from the heat pump body 1, that is, there is a certain distance between the first sound insulation barrier 2 and the heat pump body 1. Specifically, in order to play the role of sound insulation and heat preservation, heat can be accumulated to insulate the evaporator on the side of the heat pump body 1. The first sound insulation barrier 2 includes a mounting frame 21, which is frame-shaped, supported on the roof surface of the building, and has a width not less than the width of the heat pump body 1, combined with Figure 2 and Figure 3 A rock wool stabilizing frame 22 is built inside the mounting frame 21, and heat storage rock wool 23 is installed inside the rock wool stabilizing frame 22. The rock wool stabilizing frame 22 is used to fix the heat storage rock wool 23, and the rock wool stabilizing frame 22 can be installed with the mounting frame 21 by welding or bolt connection.

[0030] Based on the above structure, combined with Figure 2 , Figure 2 It is a side view inside the first sound insulation barrier 2 on the left side, and does not include the first sound insulation barrier 2 on the left side. A plurality of second sound insulation barriers 4 are installed on the upper end of the heat pump body 1, and the plurality of second sound insulation barriers 4 are arranged at intervals. The bottom end of the second sound insulation barrier 4 is located above the fan cover 5 of the heat pump body 1, that is, a certain gap is set between the fan at the upper end of the heat pump body 1 to avoid direct contact with the fan and affect the normal operation of the fan. The second sound insulation barrier 4 is mainly used to absorb the noise generated by the fan at the upper end, and a guide channel is formed between the arrangement, which can guide the cold air discharged by the fan, and in order to facilitate the installation of the second sound insulation barrier 4, the A square steel bracket 7 is provided at the upper end of the heat pump body 1, and a plurality of second sound insulation barriers 4 are installed on the upper end of the square steel bracket 7 and arranged at intervals on the square steel bracket 7. Moreover, the second sound insulation barrier 4 includes a fixing frame 41 built on the square steel bracket 7, and sound-absorbing cotton 42 is installed in the fixing frame 41. In order to be able to absorb sound over a larger range, the width of the fixing frame 41 is not less than the width of the top of the heat pump body 1. The sound-absorbing cotton 42 can absorb the noise generated by the fan. In order to prevent the second sound insulation barrier 4 from being too high and having poor stability, and also to play a role in sound insulation, the height of the second sound insulation barrier 4 is 1 / 3-1 / 2 of the height of the heat pump body 1.

[0031] In this embodiment, combined with Figure 2 and Figure 4In order to utilize solar energy to generate heat and provide heat for the heat pump body 1, an air collector 3 is obliquely installed on the upper end of the first sound insulation barrier 2. The air collector 3 can heat the cold air with air as the medium to provide hot air flow for the surrounding environment of the heat pump body 1. The air collector 3 includes a shell 31, and the outer end surface of the shell 31 is set as a transparent cover plate 32. A heat absorbing plate 33 is arranged in the shell 31, and an air inlet 34 and an air outlet 35 are arranged on the side away from the transparent cover plate 32. A heat storage material 36 is filled inside the side away from the transparent cover plate 32. When the heat pump body 1 is running under sunlight during the day, the storage material in the first sound insulation barrier 2 The thermal rock wool 23 accumulates heat, and the stored heat has the effect of noise reduction and heat preservation; outdoor air flows in from the air inlet 34, is heated by the heat absorbing plate 33 and exchanges heat with the heat storage material 36, and the heated air flows out from the air outlet 35 to the evaporator side. At the same time, the heated air flows through the heat storage material 36 to store the heat of the hot air. At night, the outdoor temperature drops. At this time, the heat storage material 36 releases the heat accumulated during the day, and air flows in from the air inlet 34. The heat absorbing plate 33 preheats the incoming air. Then the air flows in and is heated by the heat storage material 36. The heated air flows out from the air outlet 35 to the evaporator side, ensuring that the ambient temperature around the heat pump body 1 is not too low.

[0032] Secondly, the upper end of the air collector 3 is inclined toward one side of the heat pump body 1, and the upper end is connected to the upper end of the adjacent second sound insulation barrier 4, that is, the shell 31 is connected to the fixing frame 41, and the two can be connected by a mounting bracket. In order to facilitate the tilting of the angle of the air collector 3 to the angle that can maximize the use of sunlight, the distance between the outermost second sound insulation barrier 4 and the first sound insulation barrier 2 on the same side is greater than 0, ensuring that there is a certain gap between the outermost second sound insulation barrier 4 and the first sound insulation barrier 2, so that the air collector 3 can be installed at an angle, and in order to stabilize the bottom end of the air collector 3, an extension section 6 is vertically provided on the upper end of the first sound insulation barrier 2, and the extension section 6 faces the side of the heat pump body 1, and the bottom end of the air collector 3 is installed on the upper end surface of the extension section 6, and the two can also be connected by a mounting bracket.

[0033] On the basis of the above structure, in order to facilitate ventilation on both sides of the heat pump body 1, a plurality of ventilation holes 8 are provided at the extension section 6.

[0034] In this embodiment, a spring shock absorber 9 is provided under the heat pump body 1 to increase the shock absorption effect, prevent the heat pump body 1 from being vibrated during operation, and reduce the noise generated during vibration. The spring shock absorber 9 is connected to the steel pipe unit support 10, and the bottom end of the steel pipe unit support 10 is welded to the strip foundation embedded part 11, and the strip foundation embedded part 11 is connected to the bracket foundation 12.
